Features of Amazon EC2

Amazon EC2 provides the following features:

·         Virtual computing environments, known as instances

·         Preconfigured templates for your instances, known as Amazon Machine Images (AMIs), that package the bits you need for your server (including the operating system and additional software)

·         Various configurations of CPU, memory, storage, and networking capacity for your instances, known as instance types

·         Secure login information for your instances using key pairs (AWS stores the public key, and you store the private key in a secure place)

·         Storage volumes for temporary data that's deleted when you stop or terminate your instance, known as instance store volumes

·         Persistent storage volumes for your data using Amazon Elastic Block Store (Amazon EBS), known as Amazon EBS volumes

·         Multiple physical locations for your resources, such as instances and Amazon EBS volumes, known as Regions and Availability Zones

·         A firewall that enables you to specify the protocols, ports, and source IP ranges that can reach your instances using security groups

·         Static IPv4 addresses for dynamic cloud computing, known as Elastic IP addresses

·         Metadata, known as tags, that you can create and assign to your Amazon EC2 resources
